CZ163094A3 - Cigarette box - Google Patents

Abstract

A packet (1) for cigarettes or for tobacco industry products, is efficiently protected from light and from the exit or penetration of moisture and loss of aroma or taste of the products which it contains, even if it is wrapped with a label (3;10) generally comprising only one layer of material, when special precautions are taken in order to form the corners of the packet. Another advantage of the proposed package is that it has several opening means (20, 21, 22), selectable by the user, allowing the latter to open his packet either like a soft packet or like a hard packet. A package of this type is particularly ecological since it is preferably made from a biodegradable material. <IMAGE>

Description

BACKGROUND OF THE INVENTION

Two types of packaging have been used to produce cigarette packs. One is a hard pack, the so-called box, the basic element of which is a thin cardboard cutout. This type of pack usually consists of a base and a lid that is foldable relative to the base. The advantage of this type is its relative strength and protection of cigarettes.The second type is a soft package, so-called soft, whose basic element is a blank made of thin paper.The package is usually provided with a tear tab, which can tear off part of the package and thus allow the consumer access to cigarettes.This box can usually not be reclosed.A soft packaging is less resource intensive, but is less rigid and offers less protection for cigarettes.On the above types of packaging complements several other layers made of different materials.The closest to cigarettes is found an anodized foil, followed by a hard or me packaging Each of these layers has a specific function: the aluminum foil is opaque and protects the cigarettes from light, the packaging of hard or soft material creates the shape of the box and its outer wall is printed with brand, manufacturer, etc., the top transparent layer sealed the box, protects the moisture, the aroma of the three layers of the box is costly in terms of taste and cigarette taste.

The cigarette packets produced so far have a number of disadvantages. The gradual processing of more complex machinery, production in terms of raw materials and remains costly from waste as a set of different materials cannot be disposed of in the same way. These boxes also have some drawbacks by removing the cigarette they must consumer, which before tear, open and separate the three layers.

Another disadvantage of the prior art is that it is based on the possibility of creating a single opening, which is usually determined by the above-mentioned type of packaging. For the user, it might be more convenient to choose the location of the box opening to allow it to remove the cigarette without gripping the filter. the ability to freely move cigarettes into a hard case without having to grasp each cigarette.

The cigarette pack described in FR-A-2.130.640 is the conventional type mentioned above. It is provided with a single means of opening at the top thereof. In FK-A-1.003.267, in one embodiment, a cigarette pack with the possibility of two identical openings on opposite edges of the top wall, which does not give the consumer particular advantages. The cigarette pack according to DE-U-1.883.769 is provided with two means for creating an opening in the top or bottom wall. Such a package solves only one of the above disadvantages. The design of the box according to US-A-2.026.477 differs from the previous one in that it can be opened in two phases and thus allows gradual removal of cigarettes. The box according to US-A-5.139.140 is a box type, the box is made of several layers However, none of the above-mentioned box types solves the problem of reducing the number of layers relative to the requirement to save raw materials and in connection with the problem of waste disposal.

? For example, a single bladder or box of only one biological requirement, and, in particular, is a cigarette product that is made of recyclable and / or material and that meets the grip and other pull of the component, preferably better degradable light impermeability, preservation of shape, interior moisture, aroma and taste of cigarettes.

The cigarette pack according to the invention is provided with more than one means for opening it and thus allows the consumer to choose the method and location of the cigarette removal.

The cigarette pack of the present invention is less resource intensive and minimizes waste in its manufacture and use.

The cigarette pack according to the invention overcomes the above-mentioned disadvantages of the prior art. Their characteristics are formulated in claims 1 to 3, the blank of which it is made, in claims 4 to 18 and one of the uses of the pack in claim 19.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a closed cigarette box 1 which is made of a single sheet of paper or blank 10. It is provided with means for opening the box 2, in this example the tear tabs 20, 21 and 22. The tear tab 20 allows to tear off the tear tab tape 20A, which is guided in one or two tear lines along the entire periphery of the box, i.e., their front and side walls. Peeling the tear strip separates the upper portion 13 from the lower portion 14 of the box 1. The second tear tab 21 allows tear-off portion 1IA. The third tear tab 22 is disposed symmetrically relative to the other and allows to tear off the bottom wall portion 12A of the box 1. The box is provided with a locking strip 11B.

The advantages of several means for opening the box 2 are illustrated in Figures 2,3A and 3B.

In Fig. 2, the cigarette box 1 is opened by pulling

This method is essentially the same as the opening method of the soft-type box so far produced. Tear lines 110 have been formed over the entire portion 11A, which will facilitate the perimeter of the opening lines. thus, the cigarette box of the blank 10, opening it to the consumer for immediate access to the cigarettes, should not be detached. Thus, as before, it is not necessary to open the other packaging layers.As the smoker avoids gripping the filter with dirty fingers. In this case, it uses a tear tab 22 to rip a portion 12A of the bottom wall 12 of the pack and remove the cigarette at the opposite end through the opening. The second way of opening the pack is not shown in FIG. .

Figures 3A and 3B show a method of opening the box by the tear tab 20. By pulling the tear tab 20, the tear tape 20A is torn off the entire periphery of the box 1, thereby separating its upper portion 13 from the lower portion 14 which contains cigarettes. The top portion 13 and the tear strip 20A may be discarded. An open cigarette pack may be used as shown in FIG. 3A, but more preferably in an external hard case 15A. An example of such a case is shown in FIG. be made of cardboard, synthetic materials, metal or other suitable materials to ensure its durability. Consumable1 would advantageously receive a rigid case when buying a soft cigarette box. Such a practice would reduce waste of raw materials. or appropriate decorations.

FIG. 4 shows a first embodiment of a blank 3 according to the invention from which the box described above is made. The blank 3 is made from a single piece, not suitably from a sheet of thin paper, but other suitable insertions 15 with a lid may be used

The material used should be easily disposable, thus suitable for recycling or biodegradable. A sheet of thin lacquered or laminated paper may also be used. Such a treatment may be made with paper, before or after the holes. and bends.

Said material on one or both sides of cutting the blank and forming the lines is used to make a soft type box, but a harder material can also be used than the box type. The blank is cut out of paper whose width corresponds to sheet or strip the width or length of the blank, the box is single-layer, the blank must be 3. sufficiently light-resistant. This eliminates the need to use aluminum foil to protect the cigarettes in the pack. As in the prior art, the blank 3 is formed into several sectors that form the walls of the box. In this example, the front and rear walls forming the front and rear walls 30A and 3OB, the side walls forming the side walls 30C and 30D, and the top and bottom walls of the box are respectively. The gluing sectors 31.31A, 31B and 31C and their adhesive strips 32. ensure that the box is closed after it has been assembled.This method of blanking does not have the right upper and lower corner sectors.This reduces the weight of the empty box but requires more complicated slots. however, the blank can be retained and formed in the manner described below. The bending lines are formed by known tools during the blank shear operation. The bends have a groove shape that facilitates bending of different sectors. The bending lines 33 define those blank sectors that are not separated by slits. The slots 3A and 34A separate the hole sectors from the adhesive sectors and allow the sectors to stick to the surfaces. The plate 3AA between the adhesive sectors 31A and 31B, which will be pushed below the upper sector of the hole 30E. This projection is part of the bonding sector 31A and forms The tear tab 2i »shown in Figs. 1 and 2.

7, there is another projection which is cut out from the edge of the opposite gluing sector 31C. 1,2 and 3A. At the level of the first projection, i.e., the tear tab 21., there is a first line of aperture 35A which is guided so that the adhesive sectors 31B and 31C can be separated. bending line section 33 between sectors 30A and 31A and across gluing sector 31A. An additional hole line 35B may be formed in gluing sector 31B that, when sector 31A is translated into sector 31B, is parallel to a portion of hole line segment 35AN and opposite side in sector 30E. aperture line 35C which, when relocating sector 30E to sector 31A, will follow the aperture line 35A. The aperture lines 35A.35B.a and 35C are identical to the tear lines 1IC of the finished box shown in FIG.

A further line of aperture 36 extends from projection 20 across sectors 30C.30B.30D.30A and 31C.to the front and side walls of the cigarette pack. .3A. The line of the aperture 36 may be arranged in a single line to form the lower skirt of the upper portion 13 of the box which can be peeled off by pulling on the tear tab

20 May

The cigarette box shown in Fig. 1 is assembled in a known manner, ie by folding the sectors on the bending lines and gluing in the gluing sectors.In the preceding example of blank 3, there is no indication of how to pull out the tongue .22. an upper portion thereof to provide the cigarette pack with this opening means.

Since the cigarette pack is made of a single and thin wrapper and must be airtight, particular attention is paid to the way of assembling its corner portions. In the above example of blank 3, the pleats in the corner portion follow the bending line. Therefore, it is preferable that the slots 34 of FIG. 4 are arranged in one of the two ways shown

4, but is an example of a slice 34 that is in the upper sector 30E. The blank 34 to the bending line 3.3 as terminated before this line by extension of the bending line 33A and 30B. The bar in Fig. 5A extends into sectors 31 of the elongated bending line dividing both at an angle of 45 degrees in Figs. 5A to 5D. 5A separates the gluing sector 31 from the one shown in the present case and the uncut section is replaced by the separating side sectors 30D formed by two parallel cuts and 30E.

33A. However, a single cut can be made in the direction of the beginning of the bending line 33A. Another embodiment of the section is shown in Fig. 5B. The section 34 is guided by shear on sector 30E, parallel to the imaginary line of said sectors. 5C and 5D, the boss 34 is formed on a portion of the bending line separating the sectors 30B and 30D.It is terminated by a 90 degree shear or a rounding. bending line 33B led to the intersection of bending lines 33. When assembling the box from the blank provided with blanks, a cross lintel, so-called translation of the shape, to ensure the airtightness of this corner described example was related to the corners defined by sectors 30B. 30D .. 30E and 31. The corner portions may also be and with respect to the airtightness of the container will also be performed in one of the methods described above.

6 is a top view of the cigarette pack 1 made of the blank 3 as described above. FIG. 6 is one or the other 33A. The top of the box, which is evident to others, that the surface of the top wall overlaps the sector 31A, whose section 21, however, the bottom wall 12 may be entirely similar to the top wall.

The airtight enclosure consists of the entire sector 30E. which includes the tear tab and vice versa.

The aspect applied equally consistently in the method of forming the lines of the holes 35A.35B, 35C

Due to the paper, it would be a groove, or respectively, the line of holes is punching.In this perforated part of the box provided by laminating perforation or 3. Cover the perforation with a thin printing part of the box that will be It is possible to make the whole surface of the blank with a layer of wax, or to choose a color to print the outer walls of the box, which would seal the perforated parts of the box. This variant is represented by the symbol A in the section of the line of the opening 36 in FIG. 4. However, it is not absolutely necessary to cover all the line openings of the sectors that overlap in this way. Only one of the sectors is covered in each overlap.

Another embodiment of the line of holes is to direct the blank 3 in the direction of the fibers. If all or most of the fibers are directed horizontally, i.e., in the B direction of FIG. 4, the line of aperture 35B and 36 and the horizontal portions of lines 35A and 35C can be omitted since the paper will not resist much more easily and The line of holes 35A and 35C perpendicular to the direction of the fibers can be replaced by bending lines to facilitate their tearing.Line lines can also be formed in a manner similar to forming bending lines. the line of the hole on the blank 3, the thickness of which is greatly increased here. The knurling knob will lightly push through the blank 37A and the one or two rotary knives that follow us will make at least one more fine notch in this portion of the blank. hole, which will be easily detachable.If the rotary knives knurling knobs will be joined by one tool, creating such a l The advantage of these two embodiments of the line of the openings of the box, since they do not perforate the blank 3.

the latter is to achieve airtightness

The aperture lines shown in Fig. 7 may be formed on the face or back of the blank 3 and thus may be located on the outer or inner walls of the box. The creasing on the outer walls may be overlapped with a thin layer 38B to make the box perfectly smooth.

8 shows another possible embodiment of the line of the opening. There is a cross-section of a portion of the blank 3 at the location of the tear tape 20A of FIGS. 1 or 3A.At adhesive tape 39A is adhered to the back line of the blank. The strip 39B can be made into a tear tab 20. By pulling on the tear tab and pulling out the tape 39B, the cigarette box is opened all over the adhesive tape section. The adhesive tape 39A and the tape 39B will also be made of recyclable and / or biodegradable material.

The aforementioned embodiments of the lines of apertures may be suitably combined according to the type of means for opening the box.

The bonding zones 32 are shown as possible examples in Fig. 4, since their shape, location and dimensions may vary according to the manner in which the blanks are made, and one skilled in the art is able to determine their design due to the need for rigid cigarette box construction. However, it is apparent that each blank is provided with it. Depending on the material used for the blank and the covering layer, the bonding zones may be replaced by suitable hot-melt materials which connect the respective sectors of the blank under the influence of temperature and / or pressure.

Another embodiment of the blank is shown in Fig. 9. It allows the box to be assembled by folding the flat and cross sectors. The arrangement of the sectors on the blank is identical to the first embodiment described above. The right upper and lower corner sectors are not in this embodiment This cross-section is provided with a second projection, which is

- 11Parts of the gluing sector. This protrusion forms the lower tear tab 22. The principal difference between this and the above-described blank is in the manner of making the slots between the upper sector 30E and the lower sector 30F, respectively, and the adjacent gluing sectors 31 or 31A. 5B.0d of the end of the section is guided at a 45 degree angle of the bending line 33B to the point of intersection of the bending lines 33. The bonding sectors 31 or 31A adjacent to the front sector 30A and the side sector 30D are In addition, there are two other bending lines 33C at 45 degrees across the sectors 31A and 32. The box made of such a blank is less breathable than the box of a blank according to the previous example. FIG. 10 is a top view of a box made of the blank. The sector 30E forming the top wall 11 is somewhat illustrative narrower to show the layer structure.

Another embodiment of the blank 2 is shown in FIG. 11. The 45C bending lines 33C are located in the upper sectors of the opening 30E and the lower sectors of the opening 30F, compared to the embodiment of the blank of FIG. The advantage of this embodiment of the blank is that there are fewer lintels on the top and bottom walls of the box, which facilitates gluing or sealing of the box.

The blank 2 in FIG. 13 differs from the above described in that it is provided with only two blades 34A.These blades form tear tabs 21 and 22 that differ from the above. This is to emphasize the choice of any shape of tear tab. In order to ensure that no further cuts are made on this blank, it is necessary to form the bending lines 33C at a 45 degree angle into each sector forming the corner portion of the box.

Due to the large number of folds in the cross, it is less breathable than the boxes made of the above-described blank.

Fig. 15 shows another embodiment of the blank 2, whose sectors are not separated by slices but only by bending lines 33C. The respective sectors of the upper and lower walls are folded in a cross-over fashion in the usual case of soft boxes. a single crescent-shaped engagement 34B is provided, which forms a tear tab 21 or 22. The fold lines 33C in the corner portions provide complete airtightness of the box. FIG. 16 is a top view of a box made of this blank.

Another possible embodiment of the blank 3 is shown in Figure 17. It is specific to the particular embodiment of the bending lines 33D which are guided at the points that will form the side edges of the box. The bending lines are creased so that the crease width corresponds to one quarter of the cigarette width. In this way, a box with rounded side edges can be assembled to suit its content. The top view of the box produced in this way is shown in Fig.18.Cutting on a light layer of laminate the side edges can be covered and / or varnished. by a few mm cut length 3. »which, due to the large number of products, will lead to a significant reduction in raw material consumption and contribute to waste reduction. Also, the tear tab 21 is provided in a different manner. The end 34A terminates at the bend line 34B as well as the other blades 34 which are connected by a 45 degree bend line 33B to the respective bend line 33D. This line does not need to be sealed, as part of sector 31A will be placed on sector 30E when assembling the box. The described box opening device is provided with an additional line of opening 34E.ie even one portion extends along the bend line 33 and two extreme the first portion is perpendicular to the first portion. The first extreme portion of the line extends as far as the line 34C and the second extreme portion is directed

The use of this means to open the box is evident from Fig. 18, in which a top view of the box provided with a retaining band 1IB of the same type as in Fig. 1a is obtained by pulling the tear tab. the opening of the opening 34C is first torn off and part of the sector 30E is released above this line. The release is facilitated by the cutting 34D in the sector 30End the other parts of the packaging are torn along the grooved lines of the opening 34E. 18, this opening of the box is provided with a securing band Fig.18 it is clear that the securing band 1IB is located on the top wall of the box and along the part of the opening line will facilitate opening of the box. 11B. Z across

34E, which thus delimit the two edge portions of the opening line 34E in sectors 30E and 31A. The bottom wall of the cigarette box 1 may also be provided with the opening means described above. This blank is further provided with bands 34 described with reference to FIGS. 11, the fold lines 33C are formed as described with reference to FIG. 11, and the tear tab 20 is part of the tear strip formed by the scoring described with reference to FIG.

Figs. 19A, 19B, and 19C illustrate several embodiments of the grooved lines of aperture 34E that have already occurred in Fig. 17. In Fig. 19A, the aperture lines do not cross sectors 31A and 30E. The aperture line in Fig. 19C, the lateral grooved opening lines are considerably wider and the central portion of the line extends below the bending line 33. These examples indicate that said means for opening the box can be adapted for easy opening in both the upper and lower portions.

For the above creased lines, the term embossed lines is used somewhere in the art.

Fig. 20 shows yet another embodiment of a blank having means for opening the upper part

14 boxes of the same type as in the example with reference to FIG. 19A.

At the end of the description, it is appropriate to summarize the basic characteristics of the blank according to the invention. It is made of a single layer of thin paper, its airtightness at the lines of openings of various designs is appropriately secured.The blank can be covered with a thin layer of laminate and / or varnish. cigarette brand, manufacturer's logo, and other customary inscriptions.

The blanks according to any of the above examples can be made without any manufacturing waste.

Examples of blanks according to the invention have been presented in connection with the description of the method of carrying out their pull tabs, hole lines, slots and hole lines. These means can be combined with each other on the same box.

By carefully shaping the blank, a cigarette pack or other tobacco pack can be formed which has a number of significant advantages over the packs produced so far. It is more ecologically advantageous, since it is less resource intensive, is made of recyclable and / or biodegradable material, The production costs of this type are lower than those of the previous types of packaging. Consumers will appreciate the advantages of such a box which, while preserving the advantages of the type used so far, will enable it to choose several ways of opening the box. .
